Frequently Asked Questions
Here are some common questions and answers about spx file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I adjust the quality of my converted audio?
A: Yes, you can adjust the quality when converting. For higher fidelity, choose formats like FLAC or WAV. If you're okay with a bit of compression, MP3 or OGG are great choices. You control the quality, you know?
Q: Is there a difference in quality between 128kbps MP3 and 320kbps MP3?
A: Yes! The 320kbps MP3 will offer better sound quality, especially on higher-end speakers or headphones. The higher the bitrate, the better the sound, but it also means the file size will be larger. It's a balance between quality and file size.
Q: What’s the difference between MP3 and OGG formats?
A: Both MP3 and OGG are great for audio compression, but OGG tends to offer better sound quality at smaller file sizes. MP3, however, is more universally accepted. It really comes down to what you prioritize—sound quality or compatibility.
Q: Can I convert audio for use in a professional presentation?
A: Yes! If you’re using audio in a presentation, you’ll want to make sure it’s in a widely accepted format like MP3 or WAV. RunConvert can help you convert your files into the best formats for presentations.
Q: Can I convert a podcast to a different format for easier listening?
A: Absolutely! If you have a podcast in a format that isn’t ideal for your device, you can convert it to MP3 or AAC to make it compatible with virtually any platform. We’ll make it easier to enjoy your podcasts wherever you are!
Q: Can I trim my audio before converting it?
A: Currently, trimming isn’t part of the conversion process, but you can easily trim your audio file before uploading it. Many free tools out there let you do that quickly, and then you can convert it.
Q: Can I convert audio to different formats for use in my audio library?
A: Yes, you can! Whether you’re building an audio library for personal or professional use, RunConvert can help you convert your files to the formats that best suit your needs—MP3, FLAC, OGG, and more.
Q: Do I need special software to convert audio with RunConvert?
A: Nope! All you need is a browser and an internet connection. RunConvert is fully web-based, so you don’t need to install any software—just upload, convert, and go!
Q: Can I convert multiple audio formats into one file?
A: You can't merge different audio formats into one file directly, but you can convert them into the same format first and then combine them. There are audio editors available to help you merge files once they’re in the same format.
Q: Is there a limit to how big my audio file can be?
A: While we support large files, it's always a good idea to keep your audio file under 200MB to ensure a smooth conversion. Large files might take a little longer, but don't worry—RunConvert will handle it!
